Share Without Oversharing


Social media is where criminals do their homework. Your posts, photos and friend lists can reveal where you live, when you are away, who your family are and the answers to your security questions. You don't need to stop posting, just post with a stranger in mind.

1See your profiles as a stranger does

Most people have never looked at their own profiles from the outside. Start there: it shows you exactly what a scammer, stalker or identity thief would see.

Do this
  1. Search your full name in quotes, with your town, and look at the results and images. Repeat with your phone number and email addresses.
  2. Open each of your profiles in a private browser window while signed out, or use the platform's “view as public” option where it has one.
  3. Ask: could someone work out where I live, where I work, when I'm away, who my family are, or my date of birth? Could they convincingly pretend to be me?

Our Personal Exposure Audit walks through this and more, and builds a plan for you.

2Tighten your privacy settings

Every major platform has a privacy checkup or privacy section. It takes a few minutes per app and is the biggest single improvement you can make.

Facebook
Settings & privacy → Privacy CheckupLimit future and past posts to Friends, hide your friend list, and restrict who can look you up by phone or email.
Instagram
Settings → Account privacyConsider a private account if you post family life. Review who can tag and mention you.
TikTok
Settings and privacy → PrivacyPrivate account, and turn off “suggest your account to others” if you don't want to be found by people who have your number.
LinkedIn
Settings → VisibilityChoose who sees your connections, email and profile photo. Keep work details useful for recruiters but not a map of your organisation.
X, Snapchat and others
Privacy and safety settingsProtect posts if you don't need a public audience, turn off location sharing (such as Snap Map), and limit who can message you.

Menu names change often. If you can't find a setting, search the app's help pages for “privacy checkup” or “private account”.

3Know what never to post

Some details are far more useful to a criminal than to your friends. Keep these out of public posts, and think twice even with friends-only audiences.

4Check photos and videos before you share

Phones can save the exact GPS location inside every photo and video. Big social networks usually remove it from what they show others, but files sent through messaging apps as documents, by email, through cloud links or shared on smaller sites often keep it.

Do this
  1. Turn off location for your camera, unless you want it for your own albums: iPhone, Settings → Privacy & Security → Location Services → Camera; Android, the Camera app's settings → Location tags.
  2. Before sharing a file outside the big social networks, check it with our Photo Metadata Inspector or Video Metadata Inspector, and remove the location.
  3. Look at the background of every photo before posting: post, letters, screens, reflections, badges and the outside of your home give a lot away.

5Control who can find, tag and contact you

Talk to your household

Your exposure includes what family and friends post about you. Agree together what doesn't get shared publicly: the house, the children's school, holidays while you're away.

6Clean up the past

Years of old posts, check-ins and profiles are still out there. You don't have to delete everything, just the parts that help a stranger.

  1. Use the platform's tool to limit all past posts to friends where offered (Facebook has one in its privacy settings).
  2. Delete or archive old posts showing your address, children's schools, ID documents or tickets.
  3. Close accounts you no longer use. Old profiles can be hijacked, or used to impersonate you.
  4. Remove personal details from your bio: birthday year, phone number, home town and employer, unless you need them there.
  5. Ask people-search sites and Google to remove your details; the Personal Exposure Audit shows how.

Check your understanding

When is the safest time to post holiday photos?

A post invites you to share your first pet's name and the street you grew up on. What is it really collecting?

A friend you're already connected to sends you a new friend request. What should you do?
